Re: MS kills UWP apps, Telephony API appears in Windows
Microsoft has long been large enough for different departments to be effectively working in opposition to each other.
Look at the way the Windows team try and introduce a coherent new design every so often, only for the Office team to create their own separate GUI system.
Or indeed there's the parts of MS who are working on Linux compatibility (like the bash subsystem, or the HyperV drivers in the Linux kernel), presumably unnoticed by their sales division.
So yes, the left had of Microsoft doesn't know what the right hand is doing, and neither of them have any idea what that tentacle over there is doing...
